Five advisors. One question. Genuine disagreement.

Decision Council assembles a panel of AI advisors inside Claude — each with opposing mandates. They analyse independently, cross-examine each other, and a Behaviourist watches for bias. You get a scored recommendation, not a single balanced-sounding answer.

The panel

Five advisors plus a Chairman orchestrator. Mandates designed to conflict.

The Optimist

Bull case
"Every constraint is a design challenge in disguise."
Makes the strongest honest case for the upside. Scores 60–100 range.

The Pessimist

Bear case
"Hope is not a strategy. What kills you is what you didn't model."
Stress-tests downside risk and failure modes. Scores 0–40 range.

The Devil's Advocate

Stress-tester
"If everyone agrees, nobody is thinking."
Challenges every position including consensus. Must oppose if all others agree.

The Pragmatist

Arbitrator
"In theory there is no difference between theory and practice. In practice there is."
Assesses implementation reality. Primary arbitrator when others deadlock.

The Behaviourist

Process auditor
"The decision is only as good as the process that produced it."
Audits reasoning quality, detects cognitive bias. Does not score — watches.

The Chairman

Orchestrator
"My job is to run the best process, not to have an opinion."
Interviews you, assembles the panel, conducts research, routes cross-examination. Never takes a side.

How a session runs

The Chairman orchestrates everything. You ask one question and get a structured recommendation.

You convene the council

/council:convene "Should I add TRST to my ISA at 160p?" — or any decision in any domain.

Chairman researches

Live web search for current data — price, earnings, analyst targets, news. Compiled into a factual research brief.

Independent analysis

Each advisor analyses through their lens, producing a 0–100 directional score with conviction level and counter-narrative.

Cross-examination

Where scores diverge by 30+ points, the Chairman routes direct challenges between advisors.

Synthesis and recommendation

Weighted score, bull/base/bear scenarios, invalidation triggers, resolution criteria, and concrete next actions.

What you actually see

Live progress as each advisor reports in, then the full synthesis.

Researching TRST — price, earnings, analyst views, news...

● The Optimist — 74/100 — "AI citation thesis is structurally underpriced at 160p"
● The Pessimist — 38/100 — "Stock halved for a reason. Grizzly report unresolved."
● The Devil's Advocate — 45/100 — "If the market saw what the Optimist sees, why is it at 160p?"
● The Pragmatist — 62/100 — "Decent entry but size small — too many unknowns"
● The Behaviourist — "Anchoring bias detected in Optimist. Process quality: 72/100"

Cross-examining: Optimist (74) vs Devil's Advocate (45)
Unresolved. Optimist proven right if FY2026 H1 revenue >15%.

Chairman's Recommendation: PROCEED WITH CONDITIONS
Weighted score: 58/100 | Conviction: Moderate
Bull (35%): AI tailwinds compound → 250p+ | Base (45%): Steady growth → 200p
Bear (20%): Grizzly thesis confirmed → 100p
Invalidated if: FY2026 revenue growth <10%

Prove you considered every angle

Tamper-evident, timestamped, exportable. Proof of process, not just a log of output.
4

Weighted scoring with formula

Configurable advisor weights that adapt based on track record. The combined weighted score resolves divided councils into a clear directional signal.

Advisors you learn to trust by name

Each advisor has a character name, portrait, and visible track record badge. After 30 sessions, you trust Elena Blackwell's conviction score, not just "the Pessimist." Choose themes: Boardroom, War Room, Think Tank.

Free: role titles. Pro: named personas with earned trust. Switching means leaving advisors you've calibrated.
